Does the device memory have to do with the amount of apps you can store on the phone or the amount you can have running in the background at a single time?
Then what's the memory that manages the amount of apps you can have running in the background? About how many apps can the Bold run without slowing down (battery life aside)
Both. BlackBerries have system memory that serves both as storage for apps and swappable memory for running them. On the Bold, you get 128 MB. The phone can run on about half of that, so the rest of the apps you install have to fir on the other half, with room left over to download data and stay running. So closing apps is good practice because less is running to take up your free memory, but deleting stuf you don't use is helpful too because it gives you more memory to start with.
